POCKET-LAMP OR LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 479,222, dated July 19, 1892.

Application filed May 18, 1891. Serial No. 393,076. (No model.)

To all whom it may concern: 2 of the casing, this ratchet-disk being pro Be it known that LNATHAN F. MATHEWSON, vided on one of its sides with a flange or drum a citizen of the United States, residing at the 12, as shown in Figs. 4 and 5, 011 which city of Providence, in the county of Proviis placed a fulminate tape 13, provided 5 dence and State of Rhode Island, have inat regular intervals with ignitible pellets vented certain new and useful Improvements or fulminates, and means for rotating or in Pocket-Lamps or Lighting Devices, of revolving the disk step by step and igniting which the following is a specification,such as one of the pellets or fulminates on the tape will enable others skilled in the art to which 13 at each successive movement of the disk. 10 it appertains to make and use the same. The means for rotating or revolving the disk This invention relates to that class of lamps 9 step by step consists of a push-pin 14, which or lighting devices which are carried in the passes through avertical slot 15 in the roundpocket and may be used for lighting cigars, ed or curved front wall 16 of the part 2 of the lamps, gas-burners, and many other similar casing. This push-pin 14 is provided at its -15 purposes, and more particularly to that subinner end with a toe or point adapted to come division thereof in which the fulminating main contact with the ratchet-teeth on the disk terial in the form of pellets is arranged and 9, and by pushing upward on the outer excarried upon a tape, and is fully disclosed in tremity of such push-pin it is caused to slide the following specification, of which the acupward or along the slot 15, and thus rotate the 20 companying drawings form a part, wherein disk through the space covered bythe lengthof similar numerals of reference designate like the slot, which is the same as the distance beor equivalent parts wherever found throughtween two of the ratchet-teeth upon the disk. out the several views, and in which A spring 17, provided with a central opening, Figure 1 represents my improved pocketis placed upon the push pin 14 inside of the 25 lamp orlightingdevice in elevation andopen, casing 2, and is held in place by a pin 18.

The lower end of this extension 22 are hinged together at 4, one of said parts, as of the spring 21 lscurved inward, as shown, 3, being provided with a reservoir or recepand the outer or upper end curved outward tacle 5, in which is placed a suitable absorband adapted to enter the opening 24 in the lid 45 ent material 6, said reservoir being provided or cover 19 and hold the same securely in with a hinged cover '7, in which is placed a place when closed. wick-tube 8, and the other part 2 being pro- In the operatlon of this device the upper vided with a ratchet-disk 9,revolubly mountend of the spring 17 comes in contact with ed on a pin or journal 10, secured to the side the lower end of the extension 22 of the spring 21 as the pin 14 is pressed upward and forces the same inward. The upper end of the extension is released from the opening 2 1 in the cover, and a spring 25 throws it back. At the same time the disk 9 is advanced one step by the inner end of the push-pin and a springscratcher 26, one end of which is secured to the extension of the front wall of the casing, through which the extension of the spring 21 passes, and the other end of which is adapted to come in contact with the pellets on the tape 13, ignites one of said pellets as the same is pushed thereunder, and the wick,which passes through the tube 8 in the hinged cover of the reservoir 5, is lighted thereby. A spring 27, secured to the casing in any desired manner, prevents the reverse movement of the disk 9 as the push-pin 14 is pressed backward preparatory to a repetition of the operation of lighting the lamp.

In order to prevent the slipping of the fulminating tape 13, the flange 12 of the disk 9, which'forms the drum upon which such tape is carried, is preferably provided, as shown in Fig. 5, with a slot 28, through which the ends of the tape are passed into the interior of the drum formed by this flange, and a spring 29,secured upon the interior and provided at its free end with a V-shaped projection adapted to enter such slot, prevents the tape from slipping out of this slot by pressing the same firmly against the sides thereof, and by this simple arrangement the tape -is kept firmly secured upon the periphery of the drum or flange 12, and the interior thereof may be used for. the storage of the unignited portion of thefulminating tape.

In the modified form of construction shown in Fig. 6 the casing or housing is made substantially rectangular in form instead of having itsfront wall 16 curved or rounded-as is the casein Fig. 1; but otherwise the mechanism and operation is similar to that of the form shown in Fig. 1.

The form of revoluble tape-carrying disk 9 shown in Fig. 5, as well as the form thereof shown in Figs. 7 and 8, may be used in either of the forms of housing shown in Figs. 1 and 6. The form of disk 9 shown inFigs. 7 and 8 differs from that shown in Fig. 5 by having no spring 29 for keeping the ends of the tape in place, but is provided in place thereof with two revoluble studs 30 and 31, secured to the disk in any desired manner, which extend inwardly therefrom to about the depth of the flange 12. These studs are preferably provided with slots 32, into which a knife is wound around said stud and fresh tape provided with fulminates drawn from the other stud into position upon the periphery of the drum of flange 12 in position to be ignited when the toothed disk carrying the flange is in position. The two sides 2 and 3 of the casing or housing are also provided at the front or open end thereof with a catch of any desired form of construction, by which the same are held closed together, when desired. The wick,rwhich passes through the wick-tube 8 in the hinged cover 7 of the reservoir 5, is of any suitable and preferred material, and should be of sufiicient length to reach to the bottom of thereservoir, so as to take up the burningfiuid freely from the absorbent therein.

It is evident that many changes and modifications in the construction, combination, and arrangement of parts" of, my improved pocket-lamp or lighting device other than those shown and described herein may be made without departing from the scope of my invention, and I do not limit myself to any particular form thereof; but,

Having fully described my invention, its construction and operation,.whatlclaim, and desire to secure by Letters Patent, is

6. In a lighting device or pocket-lamp, the combination, with a drum adapted to receive and hold secured upon its periphery, so as to be rotated therewith, a tape provided with drops or bits of fulminating material, of a reservoir adapted to receive an absorbent material, and a wick, one end of which protrudes therefrom, means for exploding the drops or bits of fulminating material one by one at a point adjacent to the protruding portion of the wick as the drum is rotated, and means for rotating the drum step by step, substantially as shown and described.

7. In a pocket-lamp or lighting device, a revoluble disk having a flange secured thereto forming a drum, said flange being provided with a slot, as 28, by which a tape provided with drops or bits of fulminating material may be secured upon the periphery of the drum formed by the flange in such manner as to be rotated with the drum, and means by which the ends of the tape may be secured within said slot, substantially as shown and described.
